Research
Intensive research is being carried out to obtain methane alcohol from wood gas, which can be used as industrial alcohol or vehicle fuel. In the medium and long term, it is also conceivable that the product gas will be processed into new fuels to replace gasoline or natural gas. The carbon and dust particles produced during the pyrolysis of the LiPRO CHP can be used in agriculture as a soil additive. Since the carbon particles have a large specific surface area, it can increase the nutrient and water storage capacity.
We are always striving to develop and optimize the process, not only limiting ourselves to the conversion process itself, but also to what takes place before and after the actual energy conversion, always keeping in mind the holistic cycle.

Topic
In the case of large quantities of residual materials such as fermentation residues or rice husks, the complete utilization chain concerning energy and material utilization has not yet been conclusively solved. Due to their contents, the thermal conversion of such biomasses results in additional requirements such as high ash contents, ash crystallization, lower ash softening temperatures, and increased emissions. For wood chips, the company LiPRO Energy GmbH has launched an efficient wood gasifier CHP plant. Many of the thermal conversion challenges mentioned above are highly dependent on conversion temperatures. The aim is to develop a gasifier CHP plant in temperature-flexible operation so that residual materials rich in ash can also be used. In this context, the overall process development of the gasifier and CHP plant is to be optimized for product gas quality and CHP plant emissions, and utilization options for the resulting ashes are to be investigated.
Aim
The company LiPRO Energy GmbH has launched an efficient wood gasifier CHP plant for wood chips. The project aims to develop a gasifier CHP plant for residual materials rich in ash.

BMWi-Project IntenseMethane – Process intensification and flexibilization of a dry fermentation plant operated with biowaste through the biological methanation of hydrogen-rich synthesis gases

Topic
The project aims to convert hydrogen-rich (synthesis) gas from a wood gasification plant to methane in an existing dry fermentation plant for organic waste. The influence of the added gases on the biological methanation as well as the achievable gas yields or conversion rates will be investigated. In addition to the coupling of an industrial dry fermentation plant with the wood gasifier, the individual process steps are to be optimized concerning the maximization of synergy effects and under the aspect of sector coupling. To achieve these goals, the gasifier will be optimized on the one hand. For this purpose, one gasifier will be converted to O2/steam operation. Through this conversion, the N2 load of the gasifier gas is greatly reduced and can be added to the dry fermentation plant. This gas will be dissolved by the large contact area in the dry fermentation plant (trickle bed) and converted by the microorganisms already present there. In addition, the excess CO2 in the dry fermentation plant is converted into methane. This will be simulated with bottled gases in the first step and then tested on an industrial scale by coupling the gasifier and the dry fermentation plant. In parallel, the system consisting of a gasifier and digester is simulated on a laboratory scale. This will allow extensive parameter studies to be carried out economically and scientific findings to be gathered in the process. Since the project has a high industrial focus, a separate work package will be dedicated to scaling and economic feasibility in addition to the parameter studies.
